Day 11. Jan 19, 2016

  • We increased the rpms on the single flywheel prototype, achieving mediocre distance and reliability. We do not prefer this design due to excessive backspin, as well as the precision machining and low tolerances required to manufacture a consistent launcher.
  • We quickly built a double-wheel prototype launcher today, which performed better than our single-wheeled launcher.
  • On the way to making this drive base complete:



Day 8. Jan 16, 2016

  • We continued prototyping today.
  • The launcher team made a flywheel shooter. They experimented with different wheels and speeds
  • The intake/defense team began prototyping an integrated ramp-intake.
  • The drivetrain team has created a base drivetrain except for the versablocks and chain and etc to get it running.
  • For now it is a 6 pneumatic wheels drivetrain with 2 cims (and ability to put one more) on each side

Day 7. Jan 15, 2016

  • We continued building field elements. The portcullis, moat, ramparts, rock wall, low bar, and platforms are all completed. We are still working on the cheval de frise, rough terrain, sally port, drawbridge, and tower.
  • The rolling chassis for the prototype drive base is fully built, however it is not yet powered.
  • Work has begun on a wooden intake prototype. Hopefully, the intake will be able to intake from the sides and front, as well as defeat several defenses.

Day 6. Jan 14, 2016

  • The shooter team continued tweaking and strengthening the prototype flywheel
  • The drive team is finishing up the drive and should be ready in 1-2 days
  • Starting to think about how it goes together and will start CAD once prototypes are finished
  • Ordred some pneumatic wheels per Allen’s suggestion. Mountain board tires are awesome apparently
  • Had a relatively low turnout so did not get as much done as expected

Day 5. Jan 13, 2016

  • We continued prototyping today.
  • The launcher team began on a prototype elastic catapult today. They managed to get it to shoot all the way to the ceiling about 15 feet ahead of the robot which is enough for the shot from the back of the courtyard
  • The intake/defense team began prototyping an integrated ramp-intake.
  • The drive team already made a mockup drive base whose wheels can easily be switched. (west coast drive)

Day 4. Jan 12, 2016

  • The team was split up into teams of 3-4 and each prototyped the drivetrain, intake, launcher and defense opener (for the doors)
  • Today, each team began listing their goals, and possible methods of achieving those goals. A plan was put in place on the schedule of the builds.
  • For example the drive team had a goal of being able to pass category A and B defenses with their drive, but still be maneuverable, fast, and lightweight.

Day 3. Jan 11, 2016

  • We continued building the field and strategizing today. We modified the tower today, making it more rigid. We also built the portcullis and low bar.
  • The bases for other defences were made with the table saw and we started laying out how we were going to build it all.

Day 2. Jan 10, 2016

  • We continued strategizing and thinking about the game today.
  • Most of today was spent building the field. We invited several other service-related school clubs, including the National Honor Society, as well as IB CAS to aid in the field construction, as this year’s field is especially complex.
  • IMG_20160110_153557

  • The field will be constructed mostly out of wood, for low cost and ease of assembly. Some crucial pieces will be made out of the real field materials.
  • Today, we constructed the tower completely, and some of the obstacles were finished.

Day 1. Jan 09, 2016

    • FRC Stronghold was announced today. We spent the majority of the time reading and reviewing the game manual.


    • We also looked at different strategies, and their merits.


    • We split the game into separate tasks, for example crossing defenses, scoring in high and low goals, and lifting. We rated each task in terms of its difficulty, point value, and the time required to achieve the task during the game. We then prioritized each task based on benefit vs opportunity cost.
    • We each presented potential designs by drawing or writing them on sticky notes. We then pasted the sticky notes on a wall and categorized them based on what they were meant to achieve.

Here are the decisions which turned out to be the most popular:

    • Drive: Pneumatic wheels, six-wheel drive, narrow width
    • Launcher: Catapult, pinball, 1 or two wheel flywheel
    • Lifting: Winch
    • Defenses: Wedge/Inverse Wedge
